PRIORITY

This application claims priority under 35 U.S.C. §119(a) to Korean Patent Application Serial No. 10-2015-0106527, which was filed in the Korean Intellectual Property Office on Jul. 28, 2015, the entire content of which is incorporated herein by reference.

BACKGROUND

1. Field of the Disclosure

The present disclosure generally relates to an electronic apparatus, and in particular, to an electronic apparatus and a method for controlling a display that displays content.

2. Background of the Related Art

Various services and additional functions provided by electronic apparatuses have been expanded. In order to increase the value of electronic apparatuses and meet the needs of users, various applications executable by the electronic apparatuses have been developed.

Accordingly, applications and programs capable of reproducing or displaying various pieces of content may be stored in an electronic apparatus, that is mobile and includes a screen having a touch function, such as a smart phone, a mobile phone, a laptop personal computer (PC), and a tablet PC. While viewing content desired by a user on the electronic apparatus, the user can not only feel various emotions, but can also transmit content to the other party through the electronic apparatus.

Conventionally, when a user desires to share the feeling of content with another person, the content and text expressing the user's feeling are separately transmitted.

Specifically, when an emotion for content is transmitted, the content is transmitted and then, text or an icon expressing the emotion is transmitted, or the text or icon expressing the emotion is transmitted and then, the content is transmitted. The content and the text or icon expressing the emotion are separately transmitted as described above, causing inconvenience to the user in that the user needs to retransmit information on the emotion as text or an icon whenever the user feels the emotion for the relevant content.

Accordingly, there is a need in which an effect according to an emotion of the user, who is viewing content, is applied to the content and the effect, according to the emotion of the user, which is applied to the content, is transmitted, and thereby, another user who receives the content can understand the emotion of the user who has transmitted the content.

SUMMARY

Therefore, aspects of the present disclosure provide an electronic apparatus and a method for controlling a display that displays content.

In accordance with an aspect of the present disclosure, a method for controlling a display by an electronic apparatus is provided. The method includes displaying content, detecting an input corresponding to the displayed content, determining an emotional level based on the detected input, and applying an emotional effect corresponding to the determined emotional level to the displayed content, and displaying the emotional effect, which is applied to the displayed content, on the displayed content.

In accordance with another aspect of the present disclosure, an electronic apparatus for controlling a display is provided. The electronic apparatus includes a display that displays content, and a control unit that detects an input corresponding to the displayed content, determines an emotional level based on the detected input, and applies an emotional effect corresponding to the determined emotional level to the displayed content, wherein the display displays the applied content.

According to an aspect of the present disclosure, in a state where a user is viewing content, an emotion of the user may be applied to the content and the emotion of the user which is applied to the content may be transmitted to another user, and thereby, another user can understand the emotion of the user, who has transmitted the content, through the received content.

According to an aspect of the present disclosure, an emotion of the user may be expressed as a level through a change in recognition of the user's face, the number of times of an input, and the like, and an emotional effect according to the emotion of the user which is expressed as the level may be applied to the content, and thereby, a content emotion effect may be visually distinguished from each other. Further, an emotional effect and content may be combined, and content to which an emotional effect is applied may be stored and thereby, the emotional effect applied to the content may be subsequently confirmed.

DETAILED DESCRIPTION

Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no limiting the present disclosure to the particular forms disclosed herein, rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In the description of the drawings, similar reference numerals may be used to designate similar elements.

As used herein, the expressions “have”, “may have”, “include”, or “may include” refer to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and do not exclude one or more additional features.

In the present disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expressions “A or B”, “at least one of A and B”, or “at least one of A or B” refer to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B. The expressions “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but do not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposed between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no elements (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be used interchangeably with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”.

The bus 110 may include, for example, a circuit that interconnects the elements 110 to 170 and delivers a communication (e.g., a control message and/or data) between the elements 110 to 170.

The processor 120 may include one or more of a central processing unit (CPU), an application processor (AP), and a communication processor (CP). The processor 120 may perform, for example, calculations or data processing related to control and/or communication by at least one of the other elements of the electronic apparatus 101.

The memory 130 may include a volatile memory and/or a non-volatile memory. The memory 130 may store, for example, commands or data related to at least one of the other elements of the electronic apparatus 101. According to an embodiment of the present disclosure, the memory 130 may store software and/or a program 140. The program 140 includes, for example, a kernel 141, middleware 143, an application programming interface (API) 145, and/or an application program (or an application) 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an operating system (OS).

For example, the kernel 141 may control or manage system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) used to execute operations or functions implemented by the other programs (e.g., the middleware 143, the API 145, and the application program 147). Also, the kernel 141 may provide an interface capable of controlling or managing the system resources by accessing the individual elements of the electronic apparatus 101 by using the middleware 143, the API 145, or the application program 147.

For example, the middleware 143 may serve as an intermediary that enables the API 145 or the application program 147 to communicate with the kernel 141 and to exchange data therewith.

For example, the middleware 143 may assign a priority, which enables the use of system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) of the electronic apparatus 101, to at least one of the application programs 147. For example, the middleware 143 may perform scheduling, load balancing, and the like, of the one or more task requests by processing the one or more task requests according to the priority assigned to the at least one of the application programs 147.

The API 145 is, for example, an interface through which the application 147 controls a function provided by the kernel 141 or the middleware 143, and may include, for example, at least one interface or function (e.g., command) for file control, window control, image processing, character control, and the like.

For example, the input/output interface 150 may serve as an interface capable of delivering a command or data, which is input from a user or another external device, to the element(s) other than the input/output interface 150 within the electronic apparatus 101. Also, the input/output interface 150 may output, to the user or another external device, commands or data received from the element(s) other than the input/output interface 150 within the electronic apparatus 101.

Examples of the display 160 may include a liquid crystal display (LCD), a light-emitting diode (LED) display, an Organic Light-Emitting Diode (OLED) display, a microelectromechanical systems (MEMS) display, and an electronic paper display. For example, the display 160 may display various pieces of content (e.g., text, images, videos, icons, symbols, etc.) to the user. The display 160 may include a touch screen, and may receive, for example, a touch input, a gesture input, a proximity input, or a hovering input provided by an electronic pen or a body part of the user.

The communication interface 170 may establish, for example, communication between the electronic apparatus 101 and an external apparatus (e.g., a first external electronic apparatus 102, a second external electronic apparatus 104, or a server 106). For example, the communication interface 170 may be connected to a network 162 through wireless or wired communication and may communicate with the external apparatus (e.g., the second external electronic apparatus 104 or the server 106).

The wireless communication may be performed by using at least one of, for example, long-term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), WiBro (Wireless Broadband), and global system for mobile communications (GSM), as a cellular communication protocol. Also, examples of the wireless communication may include short-range communication 164. The short-range communication 164 may be performed by using at least one of, for example, Wi-Fi, Bluetooth, near field communication (NFC), and global navigation satellite system (GNSS). The GNSS may include at least one of, for example, a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter “Beidou”), and a European global satellite-based navigation system (Galileo), according to a use area, a bandwidth, and the like. Hereinafter, in the present disclosure, the term “GPS” may be interchangeably used with the term “GNSS.” The wired communication may be performed by using at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), recommended standard 232 (RS-232), and a plain old telephone service (POTS). The network 162 may include at least one of communication networks, such as a computer network (e.g., a local area network (LAN), or a wide area network (WAN)), the Internet, and a telephone network.

Each of the first and second external electronic apparatuses 102 and 104 may be of a type identical to, or different from, that of the electronic apparatus 101. According to an embodiment of the present disclosure, the server 106 may include a group of one or more servers. All or some of operations performed by the electronic apparatus 101 may be performed by another electronic apparatus or multiple electronic apparatuses 102 and 104 or the server 106. When the electronic apparatus 101 needs to perform some functions or services automatically or by a request, the electronic apparatus 101 may send, to the first external electronic apparatus 102, the second external electronic apparatus 104, or the server 106, a request for performing at least some functions related to the functions or services, instead of performing the functions or services by itself, or additionally. Another electronic apparatus 102, the second external electronic apparatus 104, or the server 106 may execute the requested functions or the additional functions, and may deliver a result of the execution to the electronic apparatus 101. The electronic apparatus 101 may process the received result without any change or additionally and may provide the requested functions or services. To this end, use may be made of, for example, cloud computing technology, distributed computing technology, or client-server computing technology.

The control unit 410 may detect, for example, an input on the content displayed on the display 420. When the content is displayed on the display 420, the control unit 410 may activate the camera 430, and may recognize the face of the user through the activated camera 430. The input may include at least one of the recognition of the face of the user who views the displayed content, and a touch and a hovering on the displayed content. For example, the control unit 410 may activate the camera 430 and may detect positions of, and changes in, the eyes, nose, gaze of the eyes, and mouth of the user on the displayed content, and may determine whether the user currently laughs, currently weeps, is currently sad, or is currently happy. Such a determination basis is such that respective thresholds of facial expressions may be stored in the memory 440 and the control unit 410 may determine an emotion of the user through the thresholds and the currently-recognized face of the user. The control unit 410 may determine an emotion of the user based on a degree of the recognized facial expression of the user.

The control unit 410 may detect an input by at least one of a touch and a hovering on the display 420 that displays the content, and may determine a point (e.g., display position coordinates) at which the input has been detected. The control unit 410 may determine an emotion of the user through at least one of a duration and the number of times of a touch or a hovering. The control unit 410 may determine the number of times of a touch or a hovering during a predetermined time period, and may determine that an emotional level of the user becomes higher as the number of times of the touch or hovering increases. For example, when the content displayed on the display 420 is a photograph of a beautiful baby, while the user views the displayed content, the user may not only wear a satisfied look, but may also touch the displayed content. In this case, the control unit 410 may recognize the face of the user and may determine that the user is feeling pleasure. The control unit 410 may determine that an emotional level of the user is high, according to the degree of the facial expression of the user or the number of times of a touch.

When the detected input is at least one of a touch input and a hovering input, the control unit 410 may display an emotional effect at the touched point. Also, when the detected input is face recognition using the camera 430, the control unit 410 may analyze the gaze of the eyes of the user and may display an emotional effect at a position of the analyzed gaze of the eyes of the user. The control unit 410 may store, in the memory 440, an identifier of the content displayed on the display 420, the emotional level of the user, and coordinate information on coordinates (position) at which the emotional effect is displayed.

FIG. 5 is a flowchart illustrating a process for displaying an emotional effect on displayed content according to various embodiments of the present disclosure.

In step 510, the electronic apparatus 101 displays content on the display 420. The electronic apparatus 101 may display content, such as a photograph, a picture, and a moving image, on the display 420. When the content is displayed, the electronic apparatus 101 may activate the camera 430 and may recognize the face of the user. When a command for activating the camera 430 is received from the user in a state of displaying the content, the electronic apparatus 101 may activate the camera 430 and may recognize the face of the user. When a predetermined time period elapses after the content is displayed, the electronic apparatus 101 may activate the camera 430. The electronic apparatus 101 may determine a state of an emotion of the user, through a facial expression (e.g., eyes, nose, mouth, etc.) of the user or a change in the facial expression of the user, which is recognized through the activated camera 430. The electronic apparatus 101 may determine a state of the current facial expression of the user, through a threshold of a standard face according to an emotion which is pre-stored in the memory 440. Also, the electronic apparatus 101 may determine a current emotional degree of the user based on the recognized face of the user.

When an input is detected in step 512, in step 514, the electronic apparatus 101 determines an emotional level based on the degree of the detected input. The electronic apparatus 101 may detect an input from the user in a state of displaying the content. The input may include at least one of the recognition of the face of the user who is viewing the content, and a touch and a hovering on the displayed content. Also, the electronic apparatus 101 may detect a hovering input on the displayed content, and may determine an emotion of the user through the input by the hovering. The electronic apparatus 101 may determine an emotional level of the user based on the degree of a change in the facial expression of the user or through the number of times of a touch. For example, the electronic apparatus 101 may determine whether the facial expression of the user, which is recognized through the camera 430, is a smiling facial expression, a laughing facial expression, or an angry facial expression. Also, the electronic apparatus 101 may determine the degree of the facial expression. The electronic apparatus 101 may determine an emotion of the user based on the degree of the facial expression of the user. Further, the electronic apparatus 101 may determine an emotion of the user through at least one of a duration and the number of times of the touch or hovering. The electronic apparatus 101 may determine that an emotional level of the user becomes higher as the degree of the recognized facial expression of the user becomes higher. If the duration of the touch is greater than or equal to a threshold or when the number of times of the touch is greater than or equal to a threshold, the electronic apparatus 101 may determine that the emotional level of the user is high.

In step 516, the electronic apparatus 101 displays an emotional effect, which corresponds to the determined emotional level, on the displayed content. The electronic apparatus 101 may display the emotional effect, which corresponds to the emotional level of the user, on the displayed content, and examples of the emotional effect may include various emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like. When the input is an input by at least one of a touch and a hovering, the electronic apparatus 101 may display the emotional effect at the touched point. When the input is the recognition of the face of the user, the electronic apparatus 101 may display the emotional effect at a point where the gaze of the eyes of the user is located. The emotional effect may move on the display 420 according to a command (e.g., a touch and drag, gaze of eyes, etc.) of the user. The electronic apparatus 101 may adjust the size of the emotional effect according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, on the content. The electronic apparatus 101 may adjust the size, color, shape, and the like, of the emotional effect, according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, color, shape, and the like, on the content. Then, the electronic apparatus 101 may store the content to which the emotional effect is applied. The electronic apparatus 101 may store an identifier of the displayed content, a name of the displayed content, the emotional level of the user, and coordinate information on coordinates (position) on the display 420 at which the emotional effect is displayed. Then, when the stored content is accessed, the electronic apparatus 101 may display the emotional effect together with the content on the display 420. In this case, the displayed emotional effect may be displayed in response to the emotional level.

When content is displayed in step 610, in step 612, the electronic apparatus 101 performs an operation of the camera and may recognize a face. The display 420 may display various pieces of content (e.g., text, images, videos, icons, symbols, etc.). When the content is displayed, the electronic apparatus 101 may perform the operation of the camera 430. When the content is displayed, the electronic apparatus 101 may activate the camera 430 and may recognize the face of the user. When a command for activating the camera 430 is received from the user in a state of displaying the content, the electronic apparatus 101 may activate the camera 430 and may recognize the face of the user. Alternatively, when a predetermined time period elapses after the content is displayed, the electronic apparatus 101 may activate the camera 430. When the content is displayed on the display 420, the camera 430 may track the gaze of the eyes of the user and may determine a part of the displayed content that the user is currently viewing. The electronic apparatus 101 may determine a current emotional degree of the user through the recognized face of the user. The electronic apparatus 101 may determine a state of an emotion of the user, through a facial expression (e.g., eyes, nose, mouth, etc.) of the user or a change in the facial expression of the user which is recognized through the activated camera 430. The electronic apparatus 101 may determine a state of the current facial expression of the user, through a threshold of a standard face according to an emotion which is pre-stored in the memory 440.

In step 614, the electronic apparatus 101 determines an emotional level through the recognized face. The electronic apparatus 101 may detect an input from the user in a state of displaying the content. The input may include the recognition of the face of the user who is viewing the content. The electronic apparatus 101 may determine an emotion and the emotional level of the user based on the degree of a facial expression of the user or the degree of a change in the facial expression of the user. For example, the electronic apparatus 101 may determine whether the facial expression of the user, which is recognized through the camera 430, is a smiling facial expression, a laughing facial expression, or an angry facial expression. Also, the electronic apparatus 101 may determine the degree of the facial expression. The electronic apparatus 101 may determine that the emotional level of the user becomes higher as the degree of the recognized facial expression of the user becomes higher. For example, when the content displayed on the display 420 is a photograph of a beautiful baby, the user may wear a satisfied look while viewing the displayed content. In this case, the electronic apparatus 101 may recognize the face of the user and may determine that the user is feeling pleasure. The electronic apparatus 101 may determine that the emotional level of the user is high or low, according to the degree of the facial expression of the user. The electronic apparatus 101 may analyze whether a sound detected from the user, who is viewing the content, through the microphone 288 is the sound of laughter or the sound of weeping and may determine that the user is currently laughing or weeping, and may determine the emotional level of the user through such a determination basis.

In step 616, the electronic apparatus 101 displays an emotional effect, which corresponds to the determined emotional level, on the displayed content. The electronic apparatus 101 may display the emotional effect, which corresponds to the emotional level of the user, on the displayed content, and examples of the emotional effect may include various emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like. Also, the emotional effect according to an embodiment of the present disclosure may not only include the above-described emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like, but may also include various pieces of information capable of expressing an emotion of the user. The electronic apparatus 101 may analyze the face or the gaze of the eyes of the user, which has been recognized in step 612, and may display the emotional effect at a point where the analyzed gaze of the eyes of the user is located. The emotional effect may move on the display 420 according to a command (e.g., a touch and drag, gaze of eyes, etc.) of the user. The electronic apparatus 101 may adjust the size of the emotional effect according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, on the content. The electronic apparatus 101 may adjust the size, color, shape, and the like, of the emotional effect, according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, color, shape, and the like, on the content.

When an input for storing the displayed content is received in step 618, in step 620, the electronic apparatus 101 stores an identifier of the content, the emotional level, and coordinate information of the emotional effect. Then, the electronic apparatus 101 may store the content to which the emotional effect is applied. The electronic apparatus 101 may store an identifier of the displayed content, the emotional level of the user, and coordinate information on coordinates (position) on the display 420 at which the emotional effect is displayed. Then, when the stored content is accessed, the electronic apparatus 101 may display the emotional effect together with the content on the display 420. In this case, the displayed emotional effect may be displayed in response to the emotional level.

Then, when the stored content is accessed, the electronic apparatus 710 may display the emotional effect together with the content on the display 420. In this case, the displayed emotional effect may be displayed in response to the emotional level.

FIG. 8 is a flowchart illustrating a process for displaying an emotional effect corresponding to a touch on displayed content according to various embodiments of the present disclosure.

When an input by a touch or a hovering is generated in step 812 in a state of displaying the content in step 810, in step 814, the electronic apparatus 101 determines an emotional level based on the detected input by at least one of the touch and the hovering.

The display 420 may display various pieces of content (e.g., text, images, videos, icons, symbols, etc.). The electronic apparatus 101 may detect an input by a touch or a hovering from the user in a state of displaying the content. The electronic apparatus 101 may determine the number of times of the input or the strength of the input. When the content has been displayed on the display 420, the electronic apparatus 101 may track a point on the display 420 where the input by the user has been detected, and may determine a part of the displayed content at which the user has made the input. The electronic apparatus 101 may determine a current emotional degree of the user through the recognized input by the user. The electronic apparatus 101 may determine a state of an emotion of the user, through the number of times of the input or the strength of the input which is recognized. The electronic apparatus 101 may determine a state of a current emotion of the user, through a threshold according to an emotion which is pre-stored in the memory 440. For example, when the number of times of the input exceeds a predetermined threshold, the electronic apparatus 101 may determine that a current emotional level of the user is high.

The electronic apparatus 101 may determine an emotional level based on the detected input by at least one of the touch and the hovering, in step 814. The electronic apparatus 101 may detect an input from the user in a state of displaying the content. The input may include an input by a touch or a hovering performed by the user who is viewing the content. The electronic apparatus 101 may determine an emotion and an emotional level of the user through the number of times of the input or the strength of the input. Also, the electronic apparatus 101 may determine the degree of the input. The electronic apparatus 101 may determine that the emotional level of the user becomes higher as the degree of the input becomes higher. For example, when the content displayed on the display 420 is a photograph of a beautiful baby, the user may make an input by a touch or a hovering at an optional point on the display 420 so as to express a satisfied emotion while the user views the displayed content. In this case, the electronic apparatus 101 may recognize the input and may determine that the user is feeling pleasure. The electronic apparatus 101 may determine whether the emotional level of the user is high or low, according to the degree of the input. The electronic apparatus 101 may analyze the number of times of a touch, the strength of the touch, or the strength of a hovering from the user who is viewing the content and may determine whether the user is currently laughing or weeping, and may determine the emotional level of the user through such a determination basis.

In step 816, the electronic apparatus 101 displays an emotional effect, which corresponds to the determined emotional level, on the displayed content. The electronic apparatus 101 may display the emotional effect, which corresponds to the emotional level of the user, on the displayed content, and examples of the emotional effect may include various emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like. Also, the emotional effect according to an embodiment of the present disclosure may not only include the above-described emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like, but may also include various pieces of information capable of expressing an emotion of the user. The electronic apparatus 101 may analyze the input recognized in step 812 and may display the emotional effect at a point where the input has been detected. The emotional effect may move on the display 420 according to a command (e.g., a touch and drag, gaze of eyes, etc.) of the user. The electronic apparatus 101 may adjust the size of the emotional effect according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, on the content. The electronic apparatus 101 may adjust the size, color, shape, and the like, of the emotional effect, according to the emotional level of the user, and may display the emotional effect, which has the adjusted size, color, shape, and the like, on the content.

When an input for storing the displayed content is received in step 818, in step 820, the electronic apparatus 101 stores an identifier of the content, the emotional level, and coordinate information of the emotional effect. Then, the electronic apparatus 101 may store the content to which the emotional effect is applied. The electronic apparatus 101 may store an identifier of the displayed content, the emotional level of the user, and coordinate information on coordinates (position) on the display 420 at which the emotional effect is displayed. Then, when the stored content is accessed, the electronic apparatus 101 may display the emotional effect together with the content on the display 420. In this case, the displayed emotional effect may be displayed in response to the emotional level.

FIG. 9A is a view illustrating an example of displaying content according to various embodiments of the present disclosure. FIG. 9B is a view illustrating an example of displaying an emotional effect together with content in response to a touch in a state of displaying the content. FIG. 9C is a view illustrating an example of displaying an emotional level of a user in response to a touch. FIG. 9D is a view illustrating an example of applying an emotional level to content. FIG. 9E is a view illustrating an example of storing content to which an emotional level is.

Referring to FIGS. 9A and 9B, an electronic apparatus 910 may display the content 912 on the display 420. The electronic apparatus 910 may display content, such as a photograph, a picture, a moving image, on the display 420. The electronic apparatus 910 may detect an input by a touch or a hovering from the user in a state of displaying the content 912. When the user views the displayed content 912, the user may, for example, express an emotion of the user through the input using the touch or hovering. For example, the user may express that an emotional level of the user becomes higher as the number of times of a touch increases. The electronic apparatus 910 may determine a state of the emotion of the user, through the input by the user. As described above, the electronic apparatus 910 may determine the current emotion of the user through the recognized input by the user, and may determine an emotional degree of the user through the input by the user. When the emotional degree of the user has been determined, the electronic apparatus 910 may display an emotional effect 913 on the displayed content 912. For example, when the content 912 is a photograph of a beautiful baby and the user performs an input by a touch or a hovering while viewing the photograph of the beautiful baby, the electronic apparatus 910 may determine the emotion of the user and may display the emotional effect (e.g., heart) 913 on the displayed content 912. The emotional effect 913 may be displayed at an optional position on the display 420, or may be displayed at a point where the input by the user is detected. Also, the emotional effect 913 may have a position adjusted according to a touch and drag of the user. Further, the emotional effect 913 may have a size and a color adjusted according to the user. Further, the heart 913 is only an example of the emotional effect, and embodiments of the present disclosure may display various emotional effects capable of expressing an emotional state of the user. The emotional effect may have a color, a size, a shape, and the like, adjusted according to an emotional level of the user.

Referring to FIG. 9C, an emotional effect according to an embodiment of the present disclosure may be displayed according to an emotional level of the user. The electronic apparatus 910 may display an emotional effect, which corresponds to the emotional level of the user, on the displayed content, and examples of the emotional effect may include various emoticons, icons, and characters, such as a heart symbol, a lightning symbol, and the like. The emotional effects may be displayed according to the emotional level. For example, when the number of times of an input by the user is equal to 1, the electronic apparatus 910 may display an emotional effect corresponding to level 1. When the number of times of the input by the user is equal to 2, the electronic apparatus 910 may display an emotional effect corresponding to level 2. When the number of times of the input by the user is equal to 3, the electronic apparatus 910 may display an emotional effect corresponding to level 3. The number of times of the input by the user according to each level may be adjusted. As a result of recognizing the input by the user, for example, level 1, which is a case where the number of times of the input by the user is equal to 1 or the input is made for 3 seconds, is a case where an emotional degree of the user is low, and a relatively large heart 920 may be displayed. Also, for example, level 2, which is a case where the number of times of the input by the user is equal to 2 or the input is made for 5 seconds, is a case where the emotional degree of the user is normal, and a relatively large heart 930 and a relatively small heart 931 may be displayed. Further, for example, level 3, which is a case where the number of times of the input by the user is equal to 3 or the input is made for 7 seconds, is a case where the emotional degree of the user is high, and a relatively large heart 940 and multiple relatively small hearts 941, 942, and 943 may be displayed.

Referring to FIG. 9D, emotional effects 951, 952, 953, 954, and 955 corresponding to an emotional level according to an embodiment of the present disclosure may be applied to content 950 and may be displayed together with the content 950. For example, when the content 950 is a photograph of a beautiful baby and the user inputs a touch or a hovering on the photograph while viewing the photograph of the beautiful baby, the electronic apparatus 910 may determine the input by the user, and may display an emotional effect on the displayed content 950. The emotional effect may be expressed as multiple hearts 952, 953, 954, and 955, or may be expressed as a bar shape 951 displayed around the content according to the emotional level. The hearts 952, 953, 954, and 955 or the bar shape 951 may have a size or the degree of increase in length depending on the emotional level. The emotional effects 951, 952, 953, 954, and 955 may each have a color, a size, a shape, and the like, adjusted according to the emotional level or emotional degree of the user. Also, the heart may be displayed at a point where the touch or hovering by the user is detected.

Referring to FIG. 9E, the content to which the emotional effect corresponding to the emotional level is applied according to an embodiment of the present disclosure, may be stored in the memory 440. The electronic apparatus 910 may store, in the memory 440, an identifier of the content 912 displayed on the display 420, the emotional level of the user, and coordinate information on coordinates (position) at which the emotional effect is displayed. When the emotional effect is applied to the displayed content, the electronic apparatus 910 may store an identifier of the displayed content, whether the emotional effect is applied to the displayed content, the emotional level, and coordinate information of a point where the emotional effect is displayed. Then, when the stored content is accessed, the electronic apparatus 910 may display the emotional effect together with the content on the display 420. In this case, the displayed emotional effect may be displayed in response to the emotional level.
